HOSE-COUPLING.

couplers, whereby the two parts may be locked together 'to prevent uncoupling when it is desired to have them hold together.

In the accompanying drawings :Figure I is a top plan view of a twoart hose cou ler provided with my locking evice. Fig. I is a side elevation of the subject matter of Fig. I. Fig. III is a central longitudinal section, as of Fig. I, showing one of the locking members engaged in the locking position, and the other elevated out of such position.

Referring to the numerals on the drawing, 1 indicates one part of a hose coupling and 2 the other part thereof, of a type well known in use, and which are in practice made interchangeable. Each is provided with a lug 3,

with which a lug 4, projecting from a wing 5 on the other, engages to hold the two parts in the coupled position. When the two parts are united to hose terminals and to each other, respectively, so as to'hang in the position, shown for example in Fig. II, they.

old together by reason of their own weight and relative structure, but if they be lifted from below, they tend to turn one upon the other, and to become uncoupled. Such a lifting of two cou led members in (practice might inadvertent y occur and pro uce accidental uncoupling, and that my device is designed to prevent. I accordingly rovide upon the parts 1 and 2, respectively, osses 6 and 7 In the boss 6, I provide a U-sha ed hook 8, and in the boss 7, a correspont ing hook 9. One leg of each hook is movably fixed within its respective boss, while the free leg thereof is adapted by the movement of the hook to engage the boss of the adjacentpart of the coupling, when the two parts are in the relative positions shown in the draw-- It is obvious that one hook would perform the required function of locking the parts to gether, but a hook on ,each boss is provided in order to preserve the interchangeable Specification of Letters Patent.

character of the two parts of the coupling above referred to.

It is not necessary in practice that the hook or'hooks should engage closely with the boss or bosses, but only that they should hold the parts so closely together as to prevent sufhcient rocking movement between the two parts to disengage them. When the twoparts are to be designedly engaged or disengaged the hook or hooks are turned out of the way, and the-coupler is manipulated in the usual manner.

It will accordingly be seen" that I have provided a construction well adapted to attain the several ends and objects above pointed out in an exceedingly simple and efficient manner. The reciprocal parts of the cou )ler are held in tight engagement under a conditions of service and are prevented from being'accidentally disengaged in the event of the hose sections becoming straightened out or tautened as, for instance, when the cars are traversing reverse curves. The reciprocal parts of the couplermay be easily disengaged by lifting the hooks from their respective bosses and then lifting the coupler bodily to disengage the mutually interlocking parts.

As many changes could be made in the above construction and many apparently "upon the opposite side and adapted to couple a by a downward swinging movement, 0

boss upon each part, and hooks carried by the-respective bosses, the hook on each boss being adapted to engage the other boss.

2. The combination with the two parts ,of H

a hose coupling of the class described, each of which has a locking arm on one side and a locking projection upon the opposite side,

said parts being adapted to mutually engage with a downward swinging movement, of a boss upon each part and oppositely disposed U -shaped lugs u on therespective the, steam joint between the parts, com

bosses, the hook on each oss being adapted prising a boss 'on each 1riart and hooks upon to engage the other boss.

the respective bosses, t e hook on each boss 3. The combination with the two parts of I being adapted to enfiage the other boss.

5 it hose coupler of the class described, each of which has a lockingarm on one side and a locking projection upon the opposite side, parts being'adapted to mutually en gf'agethrough relative rocking movements 10 thereof, of a locking device located above In testimony of'al subscribed my name. v
